PDFRenderer는 pdf파일을 page단위로 java.awt.Image 개체로 만듭니다.

---------------- 간략한 소스 설명 ----------------
// draw the first page to an image
PDFPage page = pdffile.getPage(2);

위의 코드가 pdf의 특정 page를 선택하는 부분입니다. 2페이지를 선택했습니다.

pdffile.getNumPages();
위의 코드로 pdf파일의 총 페이지 수를 알 수 있습니다.

총 페이지 수로 for문을 돌리면 모든 페이지를 이미지로 만들 수 있을 것 입니다.

@RequestMapping("/{siteTp}/test/selectTestList.do")
public String selectTestList(HttpServletResponse response,HttpServletRequest request,
@PathVariable("siteTp") String siteTp,ModelMap model) throws Exception{

tmpPage = "/"+siteTp+"/test/testList";

// @PathVariable 을 이용하여 REST 방식의 url을 적용

//Rest 방식으로 url을 지정할 경우에

//게시판의 경우 http://~/board/[관리자ID]/[게시물ID] 호출하면 내용을 볼 수 있도록 될 것입니다.

//컨텐츠 관리의 경우 http://~/contents/[컨텐츠ID] 호출하면 내용을 볼 수 있도록 될 것입니다.

수정된 소스 부분

1. spring-context.xml 추가

<!-- 어노테이션 스캔 설정-->
<context:component-scan base-package="*" />

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" p:alwaysUseFullPath="true" />

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" p:alwaysUseFullPath="true" />

2. springmvc-context.xml

// 인터셉터 추가

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
	<property name="alwaysUseFullPath" value="true" />
	<property name="interceptors">
		<list>
			<ref bean="localeChangeInterceptor" />
		</list>
	</property>
</bean>
 
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >
	<property name="alwaysUseFullPath" value="true" />
</bean> 

3. web.xml 추가

<filter-mapping>
	<filter-name>authenticationFilter</filter-name>
    <url-pattern>*.do</url-pattern>
    <url-pattern>*.jsp</url-pattern>
    <url-pattern>/board/*</url-pattern>
</filter-mapping>

<!-- 스프링 mvc 적용 URL -->
<servlet-mapping>
	<servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
    <url-pattern>*.static</url-pattern>
    <url-pattern>/board/*</url-pattern>
</servlet-mapping>

4. @Controller (kr.test.you.board.web.BoardCtrl) 함수

@RequestMapping(value = "/board/view/{manageIdx}/{boardIdx}")
public ModelAndView boardView1(@PathVariable("manageIdx") String manageIdx, @PathVariable("boardIdx") String boardIdx, ModelMap model) throws Exception {

	Map<String, Object> resultMap = new HashMap<String, Object>();

    resultMap.put("boardIdx", boardIdx);

	resultMap.put("manageIdx", manageIdx);
    
    String resultURL = "board/view";
    
    return new ModelAndView(resultURL, "resultMap", resultMap);
}

Object params[] = {
	StringUtils.nvl(parameters.print("cc_yn"), "n"),
    StringUtils.nvl(parameters.print("aveeno_yn"), "n"),
    StringUtils.nvl(parameters.print("johnsons_yn"), "n"),

    StringUtils.nvl(parameters.print("listerine_yn"), "n"),
    StringUtils.nvl(parameters.print("nizoral_yn"), "n"),
    StringUtils.nvl(parameters.print("rogaine_yn"), "n"),
    StringUtils.nvl(parameters.print("bandaid_yn"), "n"),

    StringUtils.nvl(parameters.print("nicorette_yn"), "n"),
